S -- PRIVATIZATION OF HEAT PLANT DUE 021398 POC Christine Williams, Phone:(701) 747-5294, Fax (701) 747-4215 E-MAIL: williamscr@grandforks.af.mil, williamscr@grandforks.af.mil. This is solely for information purposes to seek out potential sources. Purchase, operate, and maintain centralized high temperature hot water plant, support tanks, distribution, and all related system components. Grand Forks Air Force Base is located in Grand Forks, North Dakota. Severe cold weather during the winter season exposes the base to extreme low temperatures for long periods of time making it highly dependent on the heating system. A modern, highly-efficient, low maintenance central heating system is desirable for these particular conditions. At the present time, this utility service is provided through the base central heating plant which has been in operation since 1956. The plant furnishes High Temp Hot Water (HTHW) to some buildings where it is converted to Mid Temp Hot Water (MTHW) by means of a heat exchanger and to other buildings where it is sent directly to the fin tube units. Through the past 40 years, the plant has not gone through any major modifications other than boiler re-tubing and refractory repair works. Boilers: There are three International Lamont boilers property of the Air Force in the plant. Two of them have a capacity of 25 million British Thermal Units per hour (MMBUH) and the other 42 MMBTU. Two of them were built in 1956 and one in 1964. These boilers are intended to be back up units in case of mechanical failure or insufficient capacity of the energy supplier to operate at extremely low temperatures. There are two additional Combustion Engineering boilers with a capacity of 20 MMBUH each, that have not been in service since 1989 because of their deteriorated condition. Tanks: There are three vertical fuel oil tanks. The tanks are located next to the plant on the east side of the building. Two of them have a capacity of 100,000 Gals. and one has a capacity of 1,000,000 Gals. Two of them were constructed in 1956 and the largest one in 1958. Piping: The distribution system is made of steel pipe. It was constructed in the late 50's early 60's. Sizes range from 1.5 inchesto 12 inches. Pumps: The system circulation is produced by eight Wilson-Snyder pumps. The pumps were manufactured in 1956 and 1964. The pumps capacities are 340 GPM, 625 GPM, and 900 GPM. Capacity Of The Plant The plant is capable of providing a maximum of 180 MMBTUH. The peak demand has been 117 MMBTUH. The average heating load during the three coldest months of winter is 90 MMBTUH. The plant operates year round. During summer season the plant furnishes heat to the domestic hot water system, HVAC applications, steam generators, and other miscellaneous equipment. The average heating load during summer season is from 20-30 MMBTUH. The supply HTHW temperature is 400 F. The return HTHW temperature is 280 F. The following requirements are to be met should a contract be contemplated: Contractor would buy existing distribution system. This would include all equipment pumps and all piping up to the heat exchanger in each individual facility. Contractor would provide new boilers required for operation. AirForce would sell or lease fuel tanks and necessary land for new facilities to the contractor. Air Force would provide fuel oil to contractor at cost, reimbursed. Contractor would operate and maintain boilers, tanks and distribution lines. The point of delivery is to heat exchanger at individual facilities. Contractor would meter consumption at plant and monthly at individual facilities in accordance with the Energy Savings Performance Contract. Primary fuel to be used is natural gas. Contractor would be responsible to obtain air emissions permit and to perform emissions compliance monitoring. (0028)
